Following up from achievements of SEMIS I and

recognizing the need for follow-up support; SEMIS I achievements: Core datasets; conceptual

database design; technical capacity for data exchange

Considering the request by Greater Mekong Sub-

region (GMS-WGE-4) in Mar ’98, and endorsement by

ministerial meeting in Sep’98, ADB approved SEMIS-

II in Dec ’99

Background

…to help GMS governments to make informed decisions regarding sustainable development through

Integrated Economic and Environmental Development Planning

Assess the availability of useful and relevant data for planning

purposes;

Increase and strengthen the capacity of the national Governments

to collect and process the information/data;

Increase the capacity of national Governments to make informed

decisions regarding development investments relating to

sustainable utilization of natural resources;

Enhance the ability of GMS national Governments to conduct

integrated economic and environmental planning with relevant

data; and

Conduct, store, manipulate, and share actual integrated planning

information using the data collected in pilot projects for some

“Hotspot” areas, such as those identified in TA 5783--REG: SEF-

GMS.

Early Warning Information Systems (EWIS)

It is product of the SEMIS I project, which involves a fairly complete database of important GIS layers like

Environment (Forest, Rivers, Wetlands etc.)

Demographic data (Population, Poverty etc.)

Infrastructure (Road, Dams etc.)

and some other ancillary information (layers)

The data is provided in different scales (1:1M, 1:5M and 1:250K) depending on the layer and the source. The data was generated by UNEP RRC.AP along with the help of MRC, WWF and other international agencies. The national agencies were the major source for the local data layers.
